Abstract: We report on the use of femtosecond spectrally resolved two colour three-pulse nonlinear spectroscopy to study the carrier relaxation in Si quantum dots. The third-order polarization for a ...

Since the dawn of philosophy, thinkers from Plato to Kant have considered how beauty affects human experience, and whether it has the power to transform our state of mind. Now, a new study from ...
